6

• Why 5G?o The Perfect Storm Software-Defined Networking (SDN) / Network Function Virtualization (NFV) / Software-Defined Radio (SDR) cm- & mm-wave Bands with Lots of Bandwidth (BW) Massive Multi-Input Multi Output (mMIMO) / Beamforming Consumer-Driven Hunger for Cheap, Fast Data Hot-Spot Density Intelligent Power Management (IPM)


SDN / NFV / SDR(SDx, Vx)

High Frequency / BW(cm-/mm-wave, Unlicensed

Spectrum, Wi-Fi)

Consumer Demand(Commodity Telecom,

IoT, $$$)

Spectral & Energy Efficiency(mMIMO,

Beamforming, IPM)


7

• Why 5G?o The Benefits Speak for Themselves

• What is 5G?o In a Nutshell


11

• Heterogeneous Networks (HetNets)o Small Cells

12

• Disaggregationo Enables Densificationo Commodity Where You Need Ito Optimize, Optimize, Optimize

• Mobile Edge Computing (MEC)o Bringing Compute to the Edgeo Buffering Common / Bandwidth Intensive Loads (i.e. – Video Streaming)

• Lots of Cool RF Stuff (outside scope for today)o mm-waveo mMIMOo SDR


A Brief Introduction to SDN/NFV

13

• The Software-Defined Data Centero Pretty self-explanatory, right?

14

• The Software-Defined Data Centero Ok, a little more realistically.

15

• Software-Defined Networking (SDN)




16

• Network Function Virtualization (NFV)

17

• 5G Application: Nice or Necessity?o An Absolute Necessityo Seamless Sharing Across Base Stations & Networkso Network Slicing = Network-as-a-Service (NaaS)o Software-Defined Radio (SDR)o Service-Based Optimization


The Telco Data Center

18

• Differentiation from Typical Data Centero DC Distributiono Back-up Power (i.e. – Uptime)o Network Equipment – Building System OR NEBS Requirements (i.e. – More Ruggedized

HW)

• Where are the watts being consumed?o Intelligent Power Management (IPM)o …more on this later.

• Base station, data center, or both?

5G is Changing the Landscape

21

• 4G-LTE Has Already Brought SDN/NFV to Telco Networks

• Small Cellso Cell Network Virtualization?!? (i.e. – Bunch of Small Cells Become a Giant HetNet)o Network Slicing

• MEC Shifts Utilizationo Buffering at the Edge…more on this in a moment.


A Power Play

22

• MEC Potential for Massive Power Savingso Base Station Cachingo Tricking the Consumer Into Footing the Billo EXAMPLE: Is Grandma okay?

“Don’t worry, I’m 1.Oh wait, or am I 0?!?”

A Power Play

23

• Small Cells Yield Energy Independenceo Microgridso Fault-Toleranceo Energy Harvesting

• Disaggregation Simplifies Optimal Utilizationo Bringing Steady-State to Dynamic Load Schemeso Put Stuff to Sleep


CONCLUSIONS

24

• There is a lot of agreement on what 5G should be, but not as much on what it is and when it will fully come to fruition.

• The base station is becoming the data center.

• IPM is the key to enabling 5G!

• SDx / Vx is an integral part of the 5G data center / network and is here to stay.

• Architectural & operational shifts to the telco network will yield many paradigm shifts in power utilization.
